Seven Egyptian police officers and four militants were killed in a clash in the north of the Sinai Peninsula, the interior ministry said on Wednesday. The clash took place late on Tuesday when militants attacked forces stationed southwest of the city of Erish, the ministry said in a statement. Daesh (the so-called IS) claimed the attack, saying it had carried out simultaneous raids on military positions in Erish, according to a statement carried on the group's Amaq news agency. Security sources said the militants had used more than 10 four-wheel vehicles in coordinated attacks at four sites. Egyptian security forces have been battling militants in the Sinai Peninsula for years and launched a counter-insurgency campaign in the area in February 2018. Earlier this month militants attacked a checkpoint in North Sinai, an assault that left eight security personnel dead according to the interior ministry. Hundreds of militants have been killed along with dozens of soldiers, according to official figures which cannot be verified as Sinai is largely cut off to journalists. Egypt is currently on high alert as it hosts the Africa Cup of Nations, although none of the games are taking place in Sinai. A month before the tournament kicked off, a tourist bus was hit by a roadside bomb near the famed pyramids of Giza. A similar attack in December killed three Vietnamese holidaymakers and an Egyptian tour guide. The country's security forces and Christian minority have also been targeted by attacks. — Agencies
